Procedure

Use cones to mark out three lines as per the diagram above; 20 meters and 2.5 endurance test or 5 meters recovery test apart. The subject starts on or behind the middle line, and begins running 20 m when instructed by the cd. This subject turns and returns to the starting point when signaled by the recorded beep. There is a active recovery period 5 and 10 seconds respectively for the endurance and recovery versions of the test interjected between every 20 meter out and back shuttle, during which the subject must walk or jog around the other cone and return to the starting point. A warning is given when the subject does not complete a successful out and back shuttle in the allocated time, the subject is removed the next time they do not complete a successful shuttle.
